I'm also: hypothyroid (well replaced with all thyroid hormones), have four autoimmune diseases. BUT.....I've found that with cycling my calories and my carbs (I have a daily 'chart' that lists my cals, and macros for each day, and my highest day is 1955 calories, which is a LOT for a little person like ME...but I do NOT gain weight from it, I drop fat percentage and gain muscle ...not at the same time though).
I lost my weight lowcarb (Protein Power/Atkins rungs for addback) and keep my lowest carbs at around 40 net, and highest at around 70net. I do NOT eat starchy carbs unless it's put after a workout. I do my small amount of cardio fasted, wait and hour, and then eat a higher fibrous carb meal coupled with protein and the least amount of fat I can do.
My once a week day off/1900 and some calorie day is really fun!
For my starting routines/eats I used Tom Venuto's plan Burn Fat Feed Muscle. (It's an Ebook).





I've got a really busy day planned tomorrow, with a lot of driving. Should keep me distracted enough until tea... Here it goes!
